When you've finished wiping the coffee off your keyboard, here's the joke:

At last Gordon Brown decided to throw the towel in and resign. His cabinet colleagues decided it would be a worthy gesture to name a railway locomotive after him. So a civil servant was dispatched from Whitehall to the National Railway Museum in York, to investigate the possibilities.

"We have a number of locomotives at the NRM without names," the curator told the civil servant, "But theyre mostly freight locomotives."
"Oh dear, that's not very fitting for a former prime minister, how about that big green one, over there?" The official said, pointing to no.4472.
"Thatīs already got a name" said the curator. "Itīs called `Flying Scotsmanī."
"Oh, couldn't it be renamed?" asked the official. "This is a national museum after all, funded by the taxpayer."

"I suppose it could be considered," was the answer. "After all, the LNER renamed a number of their locomotives after directors of the company and even renamed one of them Dwight D Eisenhower."

"So thatīs settled then. Let's look at renaming 4472. But how much will it cost? We canīt spend too much, given the recession."
Well, said the consultant, "We could just paint out the `Fī."
